* [SPARC64]: More fully work around Spitfire Errata 51.David S. Miller2005-08-29
| | | | | | | | | | | | It appears that a memory barrier soon after a mispredicted branch, not just in the delay slot, can cause the hang condition of this cpu errata. So move them out-of-line, and explicitly put them into a "branch always, predict taken" delay slot which should fully kill this problem. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Make debugging spinlocks usable again.David S. Miller2005-08-29
| | | | | | | | | | | | | When the spinlock routines were moved out of line into kernel/spinlock.c this made it so that the debugging spinlocks record lock acquisition program counts in the kernel/spinlock.c functions not in their callers. This makes the debugging info kind of useless. So record the correct caller's program counter and now this feature is useful once more. Signed-off-by: David S. Miller <davem@davemloft.net>

* [SPARC64]: Revamp Spitfire error trap handling.David S. Miller2005-08-29
| | | | | | | | | | | | | | | | | | | Current uncorrectable error handling was poor enough that the processor could just loop taking the same trap over and over again. Fix things up so that we at least get a log message and perhaps even some register state. In the process, much consolidation became possible, particularly with the correctable error handler. Prefix assembler and C function names with "spitfire" to indicate that these are for Ultra-I/II/IIi/IIe only. More work is needed to make these routines robust and featureful to the level of the Ultra-III error handlers. Signed-off-by: David S. Miller <davem@davemloft.net>

* | [PATCH] convert signal handling of NODEFER to act like other Unix boxes.Steven Rostedt2005-08-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It has been reported that the way Linux handles NODEFER for signals is not consistent with the way other Unix boxes handle it. I've written a program to test the behavior of how this flag affects signals and had several reports from people who ran this on various Unix boxes, confirming that Linux seems to be unique on the way this is handled. The way NODEFER affects signals on other Unix boxes is as follows: 1) If NODEFER is set, other signals in sa_mask are still blocked. 2) If NODEFER is set and the signal is in sa_mask, then the signal is still blocked. (Note: this is the behavior of all tested but Linux _and_ NetBSD 2.0 *). The way NODEFER affects signals on Linux: 1) If NODEFER is set, other signals are _not_ blocked regardless of sa_mask (Even NetBSD doesn't do this). 2) If NODEFER is set and the signal is in sa_mask, then the signal being handled is not blocked. The patch converts signal handling in all current Linux architectures to the way most Unix boxes work. Unix boxes that were tested: DU4, AIX 5.2, Irix 6.5, NetBSD 2.0, SFU 3.5 on WinXP, AIX 5.3, Mac OSX, and of course Linux 2.6.13-rcX. * NetBSD was the only other Unix to behave like Linux on point #2. The main concern was brought up by point #1 which even NetBSD isn't like Linux. So with this patch, we leave NetBSD as the lonely one that behaves differently here with #2.

* | [PATCH] mmaper_kern.c fixes [buffer overruns]Al Viro2005-08-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - copy_from_user() can fail; ->write() must check its return value. - severe buffer overruns both in ->read() and ->write() - lseek to the end (i.e. to mmapper_size) and if (count + *ppos > mmapper_size) count = count + *ppos - mmapper_size; will do absolutely nothing. Then it will call copy_to_user(buf,&v_buf[*ppos],count); with obvious results (similar for ->write()). Fixed by turning read to simple_read_from_buffer() and by doing normal limiting of count in ->write(). - gratitious lock_kernel() in ->mmap() - it's useless there. - lots of gratuitous includes.

| | | | | | | | | | | | | | | | | | | | | | | | | | We are currently reserving one byte more than actually needed by the flash device and overlapping into the next I/O expansion bus window.

* | [PATCH] x86_64: Tell VM about holes in nodesAndi Kleen2005-08-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some nodes can have large holes on x86-64. This fixes problems with the VM allowing too many dirty pages because it overestimates the number of available RAM in a node. In extreme cases you can end up with all RAM filled with dirty pages which can lead to deadlocks and other nasty behaviour. This patch just tells the VM about the known holes from e820. Reserved (like the kernel text or mem_map) is still not taken into account, but that should be only a few percent error now. Small detail is that the flat setup uses the NUMA free_area_init_node() now too because it offers more flexibility.

| | | | | | | | | | | | | | | | | | | | | | | | | | The code to detect IO links on Opteron would not check if the node had actually memory.

* | [PATCH] i386: fix incorrect FP signal codeChuck Ebbert2005-08-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | i386 floating-point exception handling has a bug that can cause error code 0 to be sent instead of the proper code during signal delivery. This is caused by unconditionally checking the IS and c1 bits from the FPU status word when they are not always relevant. The IS bit tells whether an exception is a stack fault and is only relevant when the exception is IE (invalid operation.) The C1 bit determines whether a stack fault is overflow or underflow and is only relevant when IS and IE are set.

Here I have: $ cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 4 model name : Mobile Intel(R) Pentium(R) 4 CPU 3.33GHz stepping : 1 cpu MHz : 3320.084 cache size : 1024 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 1 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 3 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe pni monitor ds_cpl est tm2 cid xtpr bogomips : 6642.39 processor : 1 vendor_id : GenuineIntel cpu family : 15 model : 4 model name : Mobile Intel(R) Pentium(R) 4 CPU 3.33GHz stepping : 1 cpu MHz : 3320.084 cache size : 1024 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 1 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 3 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe pni monitor ds_cpl est tm2 cid xtpr bogomips : 6637.46 And the following code shows: $ cat linux-2.6.13-rc6/arch/i386/kernel/nmi.c [...] void setup_apic_nmi_watchdog (void) { switch (boot_cpu_data.x86_vendor) { case X86_VENDOR_AMD: if (boot_cpu_data.x86 != 6 && boot_cpu_data.x86 != 15) return; setup_k7_watchdog(); break; case X86_VENDOR_INTEL: switch (boot_cpu_data.x86) { case 6: if (boot_cpu_data.x86_model > 0xd) return; setup_p6_watchdog(); break; case 15: if (boot_cpu_data.x86_model > 0x3) return; Here I get boot_cpu_data.x86_model == 0x4. So I decided to change it and reboot. I now seem to have a working NMI. So, unless there's something know to be bad about this processor and the NMI. I'm submitting the following patch.
